Defining a Maturity Model for SLOs

Service Level Objectives or SLOs are a quantitative contract that describes the expected service behavior. They are often used by Organizations to prioritize the reliability, availability, coverage, and other service-level indicators of the software systems. Based on what I have learned defining and implementing SLOs, I have discovered that they are valuable when they are used to build feedback loops in two axes: adoption and automation. SLOs are a process, not a project, which imposes a need for having a framework that helps organizations to adopt a culture based on SLOs. In this talk, I am presenting a framework that allows determining the level of adoption and automation of SLOs. Based on questions related to the amount of convincing: engineering, operations, product, leadership, legal, and quality assurance, we determine the level of adoption. On the other side, considering aspects such as established and documented measurements, the level of user-centric metrics, observability strategies, and reporting toolsets, we determine the level of automation.
